The lithium-containing mineral petalite was discovered in 1800 by Jose Bonifacio de Andrada e Silva. Whilst hydrogen is commonly found in water and hydrocarbons, its main use as an element is in processing fossil fuels and fats and oils, and in the production of ammonia for food production. Two years later Antoine Lavoisier named the element hydrogene after the Greek hydro- meaning water, and -genes meaning to create or produce. In 1781, he found that water was produced when hydrogen was burned in oxygen. Hydrogen is released in reactions between acids and metals, and was identified as a distinct substance in these reactions by Henry Cavendish in 1766.
